FOUNTAIN-LAMP.

SPECIFICATION forming part of Letters Patent No. 290,001, dated December 11, 1883. Application filed May ill, 1883. (No model.) Patented in Germany May 18. 188i, No. 16,55 3, and April 2, 1892, No. 20.612.

To all whom, it may concern:

Be it known that I, VVILHELM Dnrrn, a subject of the King of Prussia, residing at Berlin, in the Kingdom of Prussia, German Empire, have invented a certain'new and useful Improvement in Fountain-Lamps, of which the following is a specification.

My improvement relates to that class of lamps in which the illuminating-oil or other 1:) fiuid is supplied from a reservoir isolated from the burner tube and elevated relatively thereto.

In the accompanying drawings, Figure 1 is a vertical section of the oil-reservoir, the fount,

the burner-tube, the burner, the feed-tube,

and appurtenances of a lamp embodying myilnprovement. Fig. 2 is a horizontal section of the fount thereof, taken at the-plane of theline 00 x of Fig. 1. Fig. 3 is an elevation of a packing-tube in the burner. Fig. 4' is an inverted plan or view of the bottom of the oilreservoir. Fig. 5 is a sectional side view, illustrative of certain parts, whereby a valve fitted to the bottom of the oil-reservoir is op 2 5 erated. Fig. 6 is a sectional side view of the lower part of the burner-tube and appurtenances, showing them tilted.

A is the oil-reservoir. It may be made of sheet metal, as usual. The bottom is pro- 0 vided with a stirrup or, frame, 1?, extending upwardly fromit. Avalvew, serving to control the egress of oil through openings in the bottom of the reservoir, has its spindle or rod f guided at the upper end in this stirrup or 3 5 frame and at the lower end in abridge, P, be

tween the said openings. A lever, h, is fulcrumed in an opening in a cylinder, 1*,extending downwardly from the bottom of the oilreservoir, and at the inner end surrounds and 40 grips the valve-rod, so that when depressed at the outer end it will raise the valve to permit the egress of oil through the openings inthe oilreservoir,which the valve controls. The outer end of this lever extends into a'slot, s, in a cy- 5 lindrical shell, 1), attached to the bottom of the oil-fount B, in such position as to be concentric with the cylinder 1'. The slot 8 has avertical portion, into which the outer end of the lever h slips when the oil-reservoiris inserted fount.

into the oil-fount, and a helical portion, into which the outer end of the lever passes when the oil-reservoir is turned around in the oilfount. When the outer end of thelever passes into the helical portion of the slot, it is. depressed, so that the inner end will raise the valve. When the valve is thus opened, the oil will flow out of the reservoir A into the fount B, and thence to the burnertube. By turning the reservoir in the reverse direction, the outer end of the lever h will beraised, and the inner end thereof, with the valve, will be depressed. The valve will be held down onits seat, when not actuated by the lever, by a spring or by means of its gravity. A collar, 9, is rigidly secured in place upon the valvespindle. At the upper end the reservoir is provided with a conical or tapering portion, 0, which fits in the mouth or upper edge of the reservoir. The helical portion of the slot 8 is longer than is necessary for the pur- 7o pose of forcing the valve 1; up from its seat, after it has forced the collar 9 up against the stirrup or frame 1?. When this occurs, the lever becomes a fixed. arm. The travel of the lever in t-he' slot, which is incident to the continued turning of the reservoir, will cause the reservoir to'be drawn down bodily into the This will result in the conical portion I O of the reservoir being wedged tightly into the mouth of thefount, so as to effectually close the latter. This is desirable, because if the lamp should fall over the oil will be prevented from flowing out of the fount.

Inside the fount B, and near the upper end of the same, a channel, 0, is formed for the admission of air. The said channel extends about three-quarters of the way around the interior of the fount, as may be seen by reference to Fig. 2. It is closed at one end, but open atthe other. Air enters it through an opening, D. extending into it, near the closed end, through the wall of the fount. It passes into the fount B at the open end of the channel. The admission of air into the fount B is necessary,in order that the oil may gradually flow out of the reservoir to the burner-tube. Owing to the peculiar construction and arrangement of the channel O,the oil will not be able to flow out of the opening D, even if the lamp should come to lie in a horizontal position, for the oil cannot flow out at the opening D before first fiowing out of the reservoir A and filling up the whole fount B, which can never occur.

I will now describe another feature of my invention,consisting in an improved packing applied to the burner for the purpose of preventing the oil from flowing at the top of the burner, in case the lamp shall be broughtinto a slanting position. This object is attained by the following arrangement: The wick F is fastened upon a traveling guide-ring, It. From this guide-rin g R a nose or pinnz, extends through a vertical slot, j, in a tube, E, and into a screw-thread on a tube, K. By turning the tube E the nose a of the guide-ring R will be caused to travel up or down the screw-thread of the tube K, and the guide-rin g will thus be raised or lowered. The tube E is connected to the chimney-gallery G byarms I; hence by turning the gallery the tube E will be turned and the wick adjusted. The upper part, c, of the tube E is enforced or thickened to such an extent that it will bear tightly against the inside surface of the burnertube M. The wick F accordingly is forced to slide strictly and tightly between the enforced and thickened part c of the tube E and the interior tube, N, of the burner. The lower end of the chimney-gallery G has formed in it a circumferential groove, into which projects a spring-catch or a screw, S, carried by an arm,

L, secured to the burner-tube M. The object of this catch or screw is to prevent the gallery from being accidentally lifted, and yet to allow it to be freely turned.

Another part of my improvement refers to an improved construction and arrangement of a valve, in combination with the feed-tube and burner-tube, for the purpose of shutting the feeding-tube whenever the lamp is tilted. The feed-tube does not communicate directly with the burner-tube; but it communicates with a chamber, Q, through an aperture, (1, in its lower portion. The burner-tube has an aperture, 1), communicating with the chamber Q. In the chamber Q, is a valve, 0, for controlling the aperture (1. It fits a small cage, (2, whereby it is guided. At the bottom of the said cage is an inwardly-turned rim, 0. A weighted lever, 1, has a head. 1, which rests upon the rim 0, and a shank, Z, which passes through the space encircled by the rim. The shank can oscillate in every direction, and has at the lower end a weighty ball, 7.. \Vhile the lamp is in an upright position the head i of the lever q rests on the rim 0, and then the valve 0 uncloses the aperture (1, permitting the oil to flow from the teed-tube through the casing Q to the burner-tube. \Vhen, however, the lamp is tilted, the weight or ball k cants the head 2' of the weighted lever upon the rim 0 and forces up the valve 0, so that it will close the aper ture a. The oil is then effectively prevented from flowing out of the burner as long as the lamp maintains a slanting position.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is-

1. In a lamp, the combination of a fount, a reservoir inserted therein, a valve for controlling the tlow of oil from the reservoir, a lever for operating the said valve, and a helical or inclined slot in a device attached to the fount, and serving to shift the lever when the reservoir is turned in the fount, substantially as specified.

2. In a lamp, the combination of a fount, a reservoir having a conical portion fitting in the mouth of the fount, and a lover or arm attached to the reservoir and extending into a helical or inclined slot in a device attached to the fount, substantially as specified.

3. In a lamp, the combination of a fount, a reservoir fitting therein, and an air-channel extending around the interior of the fount, closed at one end, open to the fount at the other end, and communicating with the external atmosphere by an aperture near the closed end, extending through the fount, sub stantially as specified.

4. In a lamp, the combination, with the burner-tube M, of the tube E, having its upper portion, 0, enforced or thickened on the outer side, substantially as specified.

5. In a lamp, the combination, with the burnertube M, of the tube E, having its upper portion, 0, enforced or thickened on the outer side, the tube K, and the guide-ring It, having a nose-piece, 12, substantially as specitied.
